yes the rect variable is called myRect, the udg stands for user defined global, a prefix all variables used in GUI have when used in Jass.
Point and Rect variables are set and removed, special effect, floating text and group variables are destroyed:
call RemoveLocation
call RemoveRect
call DestroyGroup
call DestroyForce
call [...]
Curo is right; Players are internally constants, and so they do not leak (and cannot be removed with making the player leave the game ;P).
However, in your rect/region scenario, you do not need to remove the rect. Pre-placed Regions/Rects do not leak, as they are reused. The only time RemoveRect is needed, is when you create a region/rect by converting points, or some similar method.
Although I don't know if I need to actually actively heat it or just let the plate and hotend bring the ambient temp to whatever it will, but even then I need to figure out an exfiltration for hot air. I think I kind of know what to do but it's still fucking confusing
I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
